title: [Long-term results of open stent-grafting applied with a Matsui-Kitamura( MK) stent in treatment of arch aneurysm].
abstract: We report the initial and long-term results of open stent-grafting (OSG) applied with a Matsui-Kitamura (MK) stent in the treatment of thoracic aortic aneurysm (TAA). From August 2005 to March 2013, OSG for TAA was applied in 46 cases( male/female, 36/10, 54-86 years old, mean age 71). During deep hypothermic circulatory arrest with antegrade selective cerebral perfusion, stent graft was delivered through the transected proximal aortic arch, followed by arch replacement with a 4-branched prosthesis. Operative mortality within 30 days was 6.5%(respiratory failure in 1, multiple organ failure in 1and ischemic enteritis in 1) and there was 1 in hospital death due to brain stem infarction. Perioperative morbidity included 2( 4.3%) stroke, 5( 10.9%) spinal cord injuries( paraplegia in 1, paraparesis in 1 and transient paraparesis in 3). In long-term follow-up, survival was 86.8%, 77.2%, and 72.0% for 1, 3 and 5 years. Freedom from aortic event was 97.3%, 93.8% and 89.1% for 1, 3 and 5 years. Theseresults suggested the OSG method applied with a MK stent is a useful surgical procedure for the treatment of TAA.
